--------------------------------------------
[~shwethags], I'm not sure if this is an issue with the workflow message
passing refactoring. But its something to do with the workflow builder
refactoring and I say that because the values for many attributes are "null"
strings.
{code}
-brokerImplClass
null
-brokerUrl
null
-brokerTTL
null
{code}
But, I wonder how these can be null. The code will always default to
"tcp://localhost:61616?daemon=true"
{code}
org.apache.falcon.oozie.OozieCoordinatorBuilder#createCoordDefaultConfiguration
String falconBrokerUrl = StartupProperties.get().getProperty(
WorkflowExecutionArgs.BRKR_URL.getName(),
"tcp://localhost:61616?daemon=true");
props.put(WorkflowExecutionArgs.BRKR_URL.getName(), falconBrokerUrl);
String falconBrokerImplClass = StartupProperties.get().getProperty(
WorkflowExecutionArgs.BRKR_IMPL_CLASS.getName(),
ClusterHelper.DEFAULT_BROKER_IMPL_CLASS);
props.put(WorkflowExecutionArgs.BRKR_IMPL_CLASS.getName(),
falconBrokerImplClass);
String jmsMessageTTL =
StartupProperties.get().getProperty("broker.ttlInMins",
DEFAULT_BROKER_MSG_TTL.toString());
props.put(WorkflowExecutionArgs.BRKR_TTL.getName(), jmsMessageTTL);
